3. Turn the Generator and Welder/Charger
switches on the control panel (Figure 5-2,
[A]) to their OFF positions.
4. Unplug any power cords that are plugged into
the generator panel.
5. Allow machine to run at idle for a 3-5 minutes
to allow for a cool down sequence.
6. Turn the Engine Control Switch to the OFF
position. If no air leaks are present, the
engine should start at idle speed the next
time it is started.
5.3 ENGINE THROTTLE CONTROL
FUNCTIONS
The engine speed is controlled by three factors:
1. The level of air pressure in the tank and the
position of the pilot valve switch, if
applicable.
2. The position of the welder switch on the unit
control panel, and the use of the welder.
3. The position of the generator switch on the
control panel.
Consult Table 5A: Engine Throttle Control Function
Conditions to understand how the engine speed relates
to the demand(s) of the machine system's output
functions.

Welder Operating Procedure
CC (Constant Current) Mode
CV (Constant Voltage) Mode - Using
a Voltage Sensing Suitcase Feeder
CV (Constant Voltage) Mode - Using
a Spool Gun
Consult Figure 5-3. The variable power dial adjusts the
welder amperage (30 to 205 amps), or voltage (15 to 40
volts) for the desired weld heat. Turning the power dial
clockwise increases the amperage or voltage, and
turning the power dial counterclockwise decreases the
amperage or voltage. The power dial may be adjusted
while welding.
